It seems that input issues have been resolved in spreadsheet v5.2.2, so I tried it, but I still encountered the following problems.
- If I enter full-width characters while typing in a cell, I can’t move between cells using the Enter or Tab key.
- If I enter full-width characters in a cell, trying to delete a single character with the backspace key deletes all of them.
- If I switch from full-width to half-width characters while typing in a cell, half-width characters no longer enter.
This issue occurred on Edge/Chrome on Japanese Windows.
